OK, now we finally have a real answer to the chain puzzle (from Dave Seaman). I was sorry to see that it stirred up such a fuss about infinite/indeterminant distributions. I still maintain that the range of the relevant distribution is not infinite, since "required lengths" larger than the original length of the chain can't be obtained regardless of where the chain is cut. I was also sorry to see the assumption of a particular distribution in order to obain an answer. Shouldn't there still be a best answer even with no knowledge of the distribution (possibly based on the assumption that all distributions are equally likely; that should be amusing)? When I "guessed" a uniform distribution I came up with same answer as Seaman: L/3. Interesting. Any takers on the n-piece problem, or even the 3-piece one? Seems to be quite a bit more complicated.
